This needs to carry a huge 77 inch TV. There are 4 screws like that. However, while trying to put the tv on the mount I managed to get it stuck in a weird way and the dowel broke out the wall and left a huge hole.

Can I somehow repair this whole and use it again? I don't want to move the TV elsewhere. Or should I just make two more holes in the middle of the mount and leave the corner alone?

How important is it to have lots of space between the dowels?

Can I use foam or simply mix gips to plug the whole and then just put a new dowel there?

This is how it looks:

This is the dow (rigips type):

Mount: enter image description here

The mount outer holes are about 37cm width, 10cm height.

Currently it looks like this, with only one side to the stud, hope thats reasonably safe?

Simply put, you can't reuse that type of anchor in that hole even if you patch it. The paper backing is where the strength resides, and that's compromised. Use a winged toggler if you must keep it there.

I can't imagine why you wouldn't attach to framing, though. Over and over again the question of large televisions come up on this site, and the recommendation is always to either attach to studs or overlay a rigid plate of some sort to span between studs.

Based on new information, see also How can I mount a TV tight to the wall with steel studs?

You are lucky that’s all that broke.

As noted in the comments, 4 fasteners into drywall/gypsum are completely inadequate for a heavy tv.

You need to find the studs and screw solidly into the middle of them. If your studs are placed wrong, there are plenty of questions you’ll find here where people screw plywood to studs and then the tv mount to the plywood.

Assuming you want to center the tv and there are no studs where you want to hang it. You are going to have to patch the hole from the old lag anyway, so cut a rectangle out of the sheetrock from stud to stud, wide enough to hold a 1x4 (or piece of 3/4" plywood if you need a large mount. Keep the cut-out to put back later. Mount some backing to the studs, set back so the 1x4/plywood can mount to it and the sheetrock can mount to that. Screw old sheetrock to backer board. Tape/texture to match wall. Paint. Pre-drill holes for screws to avoid any splits (not a concern if you use 3/4 ply).

Larger hole to patch, but all the same steps are necessary so it won't take any more time and will give you a secure place for mounting.
